Mass transfer in the absorption of SO_2 and NO_x using aqueous euchlorine scrubbing solution

引用

Journal of Environmental Sciences 2009年第2期21卷 155-161页

作者： DESHWAL bal-Raj LEE Hyung-Keun Department of Chemistry A.I.J.H.M. College Green-house Gas Research Center Korea Institute of Energy Research

Attempts have been made to generate euchlorine gas by chlorate-chloride process and to utilize it further to clean up SO2 and NOx from the flue gas in a lab scale bubbling reactor. Preliminary experiments were carded out to determine the gas and liquid phase mass transfer coefficients and their correlation equations have been established. Simultaneous removal of SO2 and NOx from the simulated flue gas using aqueous euchlorine scrubbing solution has been investigated. Euchlorine oxidized NO into NO2 completely and the later subsequently absorbed into the scrubbing solution in the form of nitrate. SO2 removal efficiency around 100% and NOx removal efficiency around 72% were achieved under optimal conditions. Mass balance has been confirmed by analyzing the sulfate, nitrate, euchlorine and chloride ion using ion chromatograph/auto-titrator and comparing it with their corresponding calculated values.

On the role of endogenous neurotoxins and neuroprotection in Parkinson's disease

引用

Neural Regeneration Research 2017年第6期12卷 897-901页

作者： Juan Segura-aguilar Molecular and Clinical Pharmacology ICBM Faculty of Medicine University of Chile

For 50 years ago was introduced L-3,4-dihydroxyphenylalanine（L-dopa） in Parkinson＇s disease treatment and during this significant advances has been done but what trigger the degeneration of the nigrostriatal system remain unknown. There is a general agreement in the scientific community that mitochondrial dysfunction, protein degradation dysfunction, alpha-synuclein aggregation to neurotoxic oligomers, neuroinflammation, oxidative and endoplasmic reticulum stress are involved in the loss of dopaminergic neurons containing neuromelanin in Parkinson＇s disease. The question is what triggers these mechanisms. The age of normal onset in idiopathic Parkinson＇s disease suggests that environmental factors such as metals, pollutants or genetic mutations cannot be involved because these factors are related to early onset of Parkinsonism. Therefore, we have to search for endogenous neurotoxins and neuroprotection in order to understand what trigger the loss of dopaminergic neurons. One important feature of Parkinson＇s disease is the rate of the degenerative process before the motor symptoms are evident and during the disease progression. The extremely slow rate of Parkinson＇s disease suggests that the neurotoxins and the neuroprotection have to be related to dopamine metabolism. Possible candidates for endogenous neurotoxins are alpha-synuclein neurotoxic oligomers, 4-dihydroxyphenylacetaldehyde and ortho-quinones formed during dopamine oxidation to neuromelanin. Vesicular monoamine transporter-2, DT-diaphorase and glutathione transferase M2-2 seems to be the most important neuroprotective mechanism to prevent neurotoxic mechanism during dopamine oxidation.

目前,针对环氧干式变压器浇注和干燥工序的物流系统,主要由RGV及其子车构成,其中子车作为承载工具,需要与绕组一起进入烘箱或浇注罐经历高温工艺过程。本文结合实际浇注罐和烘箱的布置情况,设计智能物流系统;在此基础上对传统RGV及其子车系统进行改造,使其子车增加升降功能;在整个生产工序中,子车只是转运载具,通过升降功能只把托盘和绕组留在烘箱或者浇注罐内。在实现相同生产工序的情况下,有效提高了生产效率,并减少了设备的投资成本。

材料热处理学报 2004年第5期25卷 41-44页

作者： MártonTakács balázsVeroe ImreFelde JianshengPan BayZoltánInstituteofMaterialsScienceandTechnology BudapestHungary SchoolofMaterialsScienceandEngineeringShanghaiJiaoTongUniversity ShanghaiChina

Possibilities of means of dilatometry in connection with production of multiphase (DP- and TRIP-) steels were examined in detail. These steels are characterized by an excellent combination of high strength and good press formability, which are essentially important in the automotive industry. Transformation processes, cooling rates, holding temperatures, composition and technological parameters play a very important role in formation of applicable microstructure of multiphase steels. Dilatometrical experiments were carried out to study the processes of intercritical annealing and hot rolling of several DP- and TRIP-steels.
